Description

Safeguard backup system, safeguard servicing unit and safeguard householder method
Technical field
The present invention relates to carry out auxiliary standby maintenance system, safeguard servicing unit and safeguard householder method for the maintenance of the Process Control System at structures such as workshop or factories.
No. 2012-191351, the Japan patented claim of the application based on August 31st, 2012 application also advocated right of priority, by its content quotation in this application.
Background technology
At present, in workshop or factory etc. (following in the situation that the two is referred to as referred to as " factory "), be built with the Process Control System for the various quantity of states of industrial process (such as pressure, temperature, flow etc.) are controlled, realize senior automatic job.In this Process Control System, mostly the field instrumentation (analyzer, manipulater) that is called as field instrument is connected via communication unit with the controller that these field instrumentations are controlled.Controller is collected the process values being obtained by field instrumentation (such as the measured value of pressure, temperature, flow etc.), corresponding to the process values of collecting, by controller, field instrumentation is operated to (control).Thus, Process Control System is carried out the control of various quantity of states.
Existing Process Control System is nearly all that the field instrumentation with analogue communication function for example, is connected via mimic transmission line (transmission line transmitting for " 4 to 20mA " signal) one to one with controller.On the other hand, Process Control System in recent years, in order to realize multifunction, is all that digitized field instrumentation for example, is connected via cable network or wireless network (field network) with controller mostly.
The design of this Process Control System, structure, maintenance, normally undertaken by several slip-stick artists.For example, the design of the operating scheme of Process Control System is undertaken by Facilities Engineer (plant engineer).For realizing the generation of specifications of the Process Control System of designed operating scheme, by system engineer, undertaken.In addition, the structure of Process Control System and maintenance are undertaken by field engineer and the system engineer's collaborative work of being responsible for each textural element (the various programs of using in field instrumentation, controller, network and Process Control System etc.) of Process Control System.
In No. 3445470 communique of Jap.P., No. 4074344 communique of Jap.P., No. 2859407 communique of Jap.P., the technology for the maintenance management of ancillary plant or Process Control System is disclosed.Specifically, in No. 3445470 communique of Jap.P., disclose following technology, that is, the computer installation pair information relevant to the improvement project of shop equipment has been stored, the status of implementation of the improvement project relevant to shop equipment has been managed.In No. 4074344 communique of Jap.P., disclose following technology, that is, by the point of Process Control System, connected and control language script automatically generates the interconnective management drawing representing between factory's key element.In No. 2859407 communique of Jap.P., disclose following technology, that is, the organically combination of a plurality of systems building in Shi factory, assists rational maintenance care based on unified information management.
The angle of effectively utilizing from equipment, requires factory can tackle neatly the variation of product or output, and the trouble free service that can (for example be more than or equal to 30 years) chronically.For the Process Control System building in factory similarly, requirement can be tackled the variation of product or output neatly, and can be more than or equal to the ground long-time running of factory's working life.
In the Process Control System of flexible operation for a long time, due to the change of deterioration, process or the material of the equipment arranging in factory, improved efficiency etc., the textural element that forms Process Control System can change continually.As previously mentioned, the maintenance of Process Control System is undertaken by field engineer and system engineer's collaborative work.Therefore,, in the situation that change forming the textural element of Process Control System, first by system engineer, carried out the operation of specifications content alteration.Then, by field engineer, carry out the operation (for example, the replacing of field instrumentation etc. or adjustment etc.) corresponding with the content of specifications after changing.
Thus, the content of Process Control System based on specifications, changes textural element.Therefore, the structure of Process Control System should be substantially identical with the content of specifications.But the real state of Process Control System (setting of actual structure or reality etc.) is not necessarily identical with the content of specifications, deviates from sometimes the content of specifications.This be due to, carrying out the system engineer of specifications content alteration operation and according to specifications content, carrying out, between the field engineer of operation, sometimes not linking up fully (or, sometimes do not need to link up fully).
For example,, in the Process Control System that the field instrumentation is in recent years connected via network with controller, as long as will just can move in field instrumentation access network.Therefore, the link position of field instrumentation and network is not so important sometimes.In this case, even if field engineer is connected to the position different from specifications content by field instrumentation, Process Control System also can normally be moved.Therefore, field engineer can not pass on its situation of having carried out the operation different from specifications content to system engineer, has produced and has deviated from therefrom between the specifications content of Process Control System and real state.
Here, even if think that the real state of Process Control System deviates from the content of specifications a little, Process Control System also can normally be moved, if do not carry out textural element change, substantially there will not be problem.But, if for a long time flexible operation, carry out textural element change continually, deviating from of the real state of Process Control System and specifications content can become large gradually.
In addition, in long playing Process Control System, sometimes also can replace the slip-stick artist who is engaged in maintenance.Therefore, also exist and cannot grasp according to the content of specifications the possibility of the real state of Process Control System.If cannot grasp the real state of Process Control System according to the content of specifications, must carry out, for confirming that real state takes industry really as, causing the upkeep operation cost plenty of time.In addition, carrying out the transformation of Process Control System or more under news, because the content of real state and instructions is different sometimes, therefore must transform or upgrade before carry out the above-mentioned industry of really taking as.
